Doplňujúce informácie
| 1. Scope |
|
1.1 This test method covers the determination of total carbon (TC), organic carbon (OC), and inorganic carbon (IC), in makeup water and high purity process water such as demineralizer effluent, condensate, and electronic grade rinse water. The tested concentration range is from 50 to 1000 [mu]g of carbon per litre. 1.2 It is the user's responsibility to ensure the validity of this test method for waters of untested matrices. 1.3 This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. |
